reboot
reboot: restart the computer.
Synopsis
reboot
Description
reboot ends every process, closing their files (so what they wrote reaches the disks), and restarts the computer: it goes off and on again, and the EEPROM boots afresh. It takes no arguments.
Exit status
It does not return when it works. If the kernel refuses, the reason is printed and the status is 1.
